Description

Electric boiling water insulation kettle

technical field

The utility model relates to a thermal insulation pot, in particular to a kettle which can not only electrically heat boiled water but also keep heat for a long time.

Background technique

At present, people generally boil water through an electric kettle, and then pour the boiled water into a thermos bottle for heat preservation and storage, which is cumbersome to operate. Therefore, someone has invented an electric kettle that can both boil water and keep warm, which is achieved by setting two heating elements—a high-power main heating element and a low-power heat-insulating heating element that are heated in a continuous cycle. The water is maintained at the set temperature range for a long time, but because there is no heat insulation measure, the water in the pot can only be boiled repeatedly to maintain the temperature, which not only affects the water quality, but also consumes electricity. So someone invented an electric kettle with only one heating element, and the kettle body is wrapped with heat insulating material or the kettle body is a double-layer structure of vacuum interlayer, which greatly improves the heat preservation effect and reduces the frequency of repeated heating. However, the bottom of the pot used for heating is a good conductor of heat, so heat will still be lost quickly from the bottom of the pot. In addition, the design of the pot lid is still a single-layer structure, and in order to avoid explosion due to excessive steam pressure in the pot when boiling water, it is usually necessary to open a steam vent hole on the pot lid or directly use the spout to exhaust the water. , but heat is also lost from the lid or spout in the heat preservation state.

Contents of the invention

In order to solve the above problems, the purpose of this utility model is to provide an electric heating kettle with good heat preservation effect and long heat preservation time.

The purpose of this utility model is achieved in the following way: an electric heating kettle for boiling water, including a lid assembly, a spout assembly, a double-layer vacuum body, a heating element, a bottom and a base from top to bottom, and is characterized in that: A heat insulation board and a heat insulation material layer are arranged in the bottom of the pot below the heating element, and the pot lid assembly is a double-layer structure with an air interlayer in the middle consisting of an upper cover and a lower cover.

The lower cover of the pot cover assembly is provided with a safety valve and an air hole for pressure relief.

The utility model is easy to use and has good heat insulation effect. Due to the good sealing performance of each part, the inside of the kettle is in a closed state during heat preservation, and the body and lid of the kettle adopt double-layer structure and the bottom of the kettle adopts heat insulation measures, so The temperature in the pot can be maintained for a long time without repeated heating, the water quality is kept good, and the electric energy is greatly saved. In addition, the safety performance is greatly increased by installing valves.

Detailed ways

As shown in FIG. 1 , the utility model includes a pot lid assembly, a spout assembly 5 , a pot body 6 , a heating element 10 , a pot bottom 23 and a base 24 from top to bottom.

As shown in Fig. 1, Fig. 2 and Fig. 3, the pot lid assembly is a double-layer structure with an air interlayer in the middle formed by an upper cover 15 and a lower cover 26. A sealing ring 2 is provided at the place corresponding to the spout assembly 5 on the lower surface of the bottom of the lower cover 26, which plays a sealing role after tightening. The outer side of the lower cover 26 is provided with an external thread, which can be screwed with the spout 5. When tightening, the position corresponding to the water outlet of the spout assembly 5 is provided with an air hole 3, which communicates with the air interlayer and the outside world. The bottom of the lower cover 26 is provided with a safety valve 1 , can make the inside of the pot communicate with the air interlayer, if the steam pressure in the pot is too high, the pressure can be released through the safety valve 1 and the air hole 3, and its safety performance is greatly improved under the condition of ensuring the seal. The spout assembly 5 is fixedly clamped on the top of the kettle body 6 , and the gap at the joint is sealed by the sealing ring 4 . A handle 21 is provided on the outside of the spout assembly 5, and a steam channel 16, a steam valve 17, and a steam pressure sensor 18 for controlling power on and off are provided at their junction. The power "on" and "off" buttons 19, 20 are located in the handle 21 and are connected to the steam pressure sensor 18 respectively. The pot body 6 is a double-layer stainless steel vacuum pot body composed of an outer shell 7 and an inner tank 8. The bottom is fixedly connected to the pot bottom 23. The bottom of the pot body is a heating area with a single-layer structure. The heating element 10 is located below the heating area and is closely connected to it. Contact, heat transfer is good, reducing heat waste. The heating element 10 is also connected with protection devices such as a fuse 9 and an anti-boil dry thermostat 13 . A heat insulating board 11 and a heat insulating material layer 22 are provided in the pot bottom 23 corresponding to the position below the heating element 10 . Kettle bottom 23 bottom centers are provided with cordless socket 12. The center of the base 24 is provided with a cordless plug 14 that matches the cordless socket 12 at the bottom of the kettle 23 .

When in use, fill the kettle with water, tighten the lid, place the kettle on the base 24, connect the cordless socket and the plugs 12 and 14, press the "on" button 19 to turn on the power, and the heating element 10 starts heating . Until the water is boiled, the steam acts on the steam pressure sensor 18 through the steam channel 16 and the steam valve 17. When the pressure of the steam reaches the set value of the sensor 18, the power is automatically cut off and the heating is stopped. The pressure sensing value of the pressure sensor 18 is used to control the boiling time of the water. After the water is boiled, the power is cut off and the heating is stopped. Due to the closed design and heat insulation measures of the utility model, the water keeps high temperature for a long time in the kettle without repeated heating. When pouring boiling water, unscrew the lid to a certain angle so that the water outlet of the lid is aligned with the spout to pour water, and then tighten the lid after pouring water, so that the kettle is in an airtight state again.
